Several similar projections utilizing cranial and caudal angulation of the X-ray tube in various obliquities have been described recently for coronary angiography and left ventriculography. These views provide improved visualization of the proximal branches of the left coronary artery, the region of the crux of the right coronary artery, and the left ventricle in the left anterior oblique projection; structures which in the conventional projections are often superimposed on one another or are foreshortened. The confusing and conflicting terms--"oblique clockwise and anticlockwise table base turn," "half-axial," "angulated," "sit up," "caudo-cranial sagittal augulation," "cranio-caudal sagittal angulation," and "lordotic" projections--should be discarded in favor of the terms "cranial angulation projection" and "caudal angulation projection." The appropriate anterior, rather than the posterior obliquity should be used to refer to rotation of the patient, or the X-ray beam around his long axis.
最近已经描述了几种类似的投照方法，在各种倾斜角度下利用X射线管的头侧和尾侧成角进行冠状动脉造影和左心室造影。这些视图能更好地显示左冠状动脉近端分支、右冠状动脉十字交叉区域以及左前斜位投照时的左心室；在传统投照中，这些结构常常相互重叠或缩短。那些令人困惑且相互矛盾的术语——“顺时针和逆时针转动检查台基座”“半轴位”“成角”“坐起”“尾到头矢状面成角”“头到尾矢状面成角”以及“脊柱前凸”投照——应该被摒弃，而采用“头侧成角投照”和“尾侧成角投照”这两个术语。应使用合适的前斜位，而非后斜位来表示患者或X射线束围绕其长轴的旋转。
